摘要
根据南俄4项目施工的实际情况,对碳质板岩类的软岩特性及其变形原因进行了分析,阐述了水工隧洞中碳质板岩在一期开挖支护过程中针对变形采取的施工处理措施,所取得的经验可为后续类似工程提供借鉴和参考。
Combined with the actual construction situation of Nam Ngum 4 Project,this paper analyzed the soft carbonaceous slate characteristics and the causes of deformation,and elaborately introduced the construction treatment measures for carbonaceous slate deformation in the first stage excavation and support process of hydraulic tunnel,so as to provide reference for subsequent similar projects.
